This preview environments driver can be used to generate random strings of any length. The config section, when using this driver, supports the following properties:

  • length [Integer, optional] - the length of the random string to generate. Defaults to 8.
  • lower [Boolean, optional] - whether to generate string with only lowercase alphabets. Defaults to false.

For example, to generate a random string of length 12 with only lowercase alphabets:

---
resources:
  - name: my-random-value
    driver: random-string
    config:
      length: 12
      lower: true

This may generate a value like bghawfdkowlk

​
Outputs

This driver outputs the generated random string using the value identifier. For instance, in the above example, the generated string can be used inside of another resource as follows:

---
resources:
  - name: my-random-value
    driver: random-string
    config:
      length: 12
      lower: true
  - name: my-deployment
    depends_on:
      - my-random-value
    source:
      name: web
    config:
      values:
        container:
          env:
            normal:
              MY_RANDOM_VALUE: "{ .my-random-value.value }"
